To all whom/it mayconcem:

Be known that I, WILLIAM P; DAY,- a citizen of the-United States, residing at Cleveland, inthe county ofCuyahoga: and State of Ohiofhave inventedcertain new andxuseful Improvements in Rail lnsulating Metallic Ties, ofwhich thefollowing is a specification.

This 'invention'vrelate's to metallicties for railroads, and particularlytothe metallic ties which are illustrated in my patents No. r 1,317 ,7 7 9, granted on the 7th day ofOctober, 1919, and No. 1,420,974, 22nd day of "Jl1I1e,'1-922. I V In these patents and in other roadhed's granted on the known to me wherejmetallic ties "are;used, all ofthe insulationhas been placedunder the rails and around the fastening's. This causes wear of the insulation because of the fact that" the insulation is placed beneath the rails) and rendersit diflicult to place "the insulation and to keep the insulation from wearing out. i 3 it p The object of the present invention isto provideasteel tie construction ofr'the same general character as ,that disclosed in my priorpatents abovereferred to but wherein the insulation is disposed at the'ini'ddle of the tie. In other words, the, tie is made in two sections and the two sections of the tie are insulated f romfeachother, thus placing the 'insul'ationat a point where it will not wear and where it is readilyapplied;

"Afurtherobject is to providea structure ofthis characteri which is thoroughly strong 7 and which" is thoroughly fitted 'for'steam railway, construction ."particularly, though not limited thereto. a

the following description.

* Other obiectswill'appear in the course of p set with relation tothe channelirons'll', the channel irons 11, having their channels facing in one direction and, the channel panying drawings, wherein H Figure 1 is a top plan view of a metallic railtie constructed in accordance with my invention; v F'gure 2: is anelevation of the tie 7 'j Figure? isi,'a"'sec'tion"on-the line 3-'-3 of F a' l; f a a -1 Figure '4 is .a' sectional view-on a horizontal planethrough-the ioining endso'f My lnvention is illustrated in the accoin the bars 11 and 11, the filler block ,being' at the overlapping ends thereof are the insui a 1n section;

Each tie comprises the supporting 'plates 10 which extend parallel to "therails andbeneath the rails: These supporting plates are made'of sheet steel "three-eighths of an inchthick,

the endsofthe plate beingso formed as to rest upon the Y transverse channel irons 11 and 11 The sidewalls of the plate extend downward and outward, as' at 12, and the plate is "formed with openings 13 for the attachment of rail fasteners 14. The plates are riveted or'otherwiseconnected to the transversely extending channel irons 11 and ll and, as heretofore stated in my prior patents, the channel irons 11 and .11 together extend entirely across the road bed andboth plates 10. wereattachedto a pair of integral channelirons. i a c In the constructionillustrated in Figure 1, the. tie is made in two sections A andB',-

these sections being alike" except that the plate 10 of the sectionrB is disposed ahead of the plate 10 of thesection A. "Riveted to the ends of the plate 1 0 of'section A are the channel irons 11, and riveted to the ends of th'e' plate 10 of the section B are the channel irons 11. These channel irons "11? are offirons" llj having their channels facing in the opposite direction, so, that whenthe extremities of the channel irons 11" are disposed in proper relation tothe channel irons 11, the channels of the channel ironsll and 11? .will faceeach. other and thej'ends of these channel irons, will extend slightly past h other toaer aterrm ss x ent Disposed between the facing channel irons wood,"though any other suitable insulating material may be. used. 'These insulating blocks are long enough to overlap both of the channel irons and fit within the channels thereof and the blocks are held to the channels by means of bolts 16, thus securing a firm splice between the overlapping ends of the channel irons and at the same time thoroughly insulating them from each other. It will be noted that by placing the blocks 15 within the channels of the connecting bars 11 and 11 that the two sections of the tie are held against independent movement in a vertical plane as well as independent movement in a horizontal plane and that the two rails are thoroughly insulated from each other and that this insuijation is disposed at the middle of the road In road beds-constructed in accordance with my invention, the middle portion thereof is covered with concrete or ballast so that this insulation is thoroughly protected from wear or damage. It is obvious that the block may be impregnated with a water-proofing compound and also coated with a water-proofing compound so that it will last indefinitely, or that other insulating materials having sufiicient strength might be usedin place of woody InFigure 6 illustrate another form of my invention, in which the transverse channel bars do not extend straight across the road bedin all places at right angles to the rails, but in which a single channel iron 11 is formed into an approximate triangle with its ends attached to the extremities of the plate 10. At the apex of the triangle, however, each channel iron is bent to form a portion 11 which extends parallel to the axis of the plate 10 and both channel irons are formed with their channels facing outward so that the channels confront each other at this portionll.

Disposed within these confronting faces I of the channel irons is the insulating block 17, which is preferablymade of hard wood, this insulating block being held by bolts 18 passing through the block and through the channel irons and bearing against filling blocks 19 which are disposed. within the re-entrant portions of the apex of the triangle, the extremities of these filling blocks being beveled so as to fit-against the web of the channel irons, By turning up on the nuts of the bolts 18, these filler blocks are forced into place, the two channel irons are forced into place against the wood block, and the two sections of the tie are held firmly engagedwith each other against any deformation. Here, again, the two sections of the tie are insulated from each other so that the rails are insulated from each othvr and this insulation occurs at the middle of thetie where the insulation will be thoroughly protected, as heretofore explained.

The construction which I have described is particularly adapted for steam railroads which carry a track circuit, and the purpose of the invention is to absolutely divorce one rail from the other. This construction is particularly desirable where steam rallroads cross highways, that is where steam railroads cross paved streets on grade, though obviously I do not wish to be limited to this use of the invention.

lVhile I have illustrated a tie of a particular form, that is the form covered by my prior patents, I do not wish to be limited to the exact details of construction as these might be changed without departing from the spirit of the invention as defined in the appended claims.

I claim 1. A metallic tie formed in two sections, each section including channel irons, the channel irons of one section extending toward the channel irons of the other section and the channel iron of one section having its channel facing the corresponding channel iron of the other section, an insulating block disposed within the channels of both sections, and fastening devices disposed through the insulating blocks and the two sections and holding them in rigid engagement with each other.

2. A metallic tie formed in two lateral sections, each section including channel iron members extending toward each other, the channel iron members having their channels facing each other for a distance, an insulating block disposed in the channels of the two channel irons, and a bolt passing through the channel irons and through the insulating block and rigidly engaging the two sections with each other.

3. A metallic tie comprising a pair of parallel rail supporting plates, channel irons extending from the ends of each of said plates toward the other plate, the channel irons of one plate confronting the channel irons of the other plate for a distance and both of said channel irons having their channels facing toward each other, a block of insulating material disposed within said channel irons but spacing them from each other, and bolts passing through the channel irons and through said block.

4. A metallic tie of the character described comprising a pair of parallel metallic rail supporting plates, channel iron members attached to the ends of each of said plates and extending toward the other plate, the channel irons of one plate overlapping the channel irons of the other plate and the channels facing toward each other, and insulating blocks disposed within the channels of adjacent channel irons and spacing the adjacent channel irons from each other and being bolted thereto.

5. A metallic tie formed in two sections, each section including rail-supporting elements, etallic members attached to each element and extending toward the other element, the members facing each other for a distance, an intermediate insulating block disposed between the confronting faces of the members and spacing the members from each other, and bolts passing through the members and blocks and holding them in engagement with the block; the block being thereby removable from between the members without shifting the members or the elements to which they areconnected.
